DC and AC parameters

Ready/Busy signal electrical characteristics

Figure 28, Figure 29 and Figure 30 show the electrical characteristics for the Ready/Busy

signal. The value required for the resistor RP can be calculated using the following equation:

RPmin= -(--V----D-----D-----m--I--O-a----xL----–-+----V----IO--L---L----m-----a----x---)-

So,

RPmin(1.8V)= 3----m--1----A.-8----5+---V-----I--L--

RPmin(3V)= 8----m----3--A-.--2--+--V------I--L--

where IL is the sum of the input currents of all the devices tied to the Ready/Busy signal. RP

max is determined by the maximum value of tr.
